Given numbers are 101,656,690,115,866
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 101,656,690,115,866 is 9897652560.
Find LCM of 101,656,690,115,866 with Prime Factorization
| 2 | 101, 656, 690, 115, 866 |
| 5 | 101, 328, 345, 115, 433 |
| 23 | 101, 328, 69, 23, 433 |
| 101, 328, 3, 1, 433 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 101 x 328 x 3 x 1 x 433 = 9897652560
Therefore, the lowest common multiple of 101,656,690,115,866 is 9897652560.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
101 x 656 x 690 x 115 x 866 = 4552920177600
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
101 : 1, 101
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
115 : 1, 5, 23, 115
866 : 1, 2, 433, 866
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 101,656,690,115,866, is 1.
Now, the common factors can be found like this.
101:101
656:2x 2x 2x 2x 41
690:2x 3x 5x 23
115:5x 23
866:2x 433
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 23 = 460
Therefore, the value for common factors is 460.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 4552920177600/(1x460)
LCM = 4552920177600/460
LCM = 9897652560
Thus, we can understand that the LCM of 101,656,690,115,866 is 9897652560.
